The "can" attached to the pole is called a "pot." At least in the U.S., four homes are normally attached to a pot. But sometimes, you might have as many as eight. When eight are attached, you will have power drops, momentary losses of electricity. Without a UPS, your desktop will turn off. Or your stereo system will--flash on and off. Intolerable. The solution is an additional pot. Or this man' solution, a pot of his own. It's not so crazy, in areas where electricity is affected by a tropical climate or... not enough pots. I learned this while struggling with electricity issues after surviving Hurricane Wilma and talking to the repair crews.
